A microstatic-bomb combustion calorimeter has been developed from a 1107 Parr semi-micro-bomb. The energy equivalent of this calorimeter is just epsilon(calor) = (687.45 +/- 0.34) J.K-1, which means an uncertainty of 0.05% for the calibration with benzoic acid NIST 39j. This combustion calorimeter has found direct application in the measurement of the enthalpy of combustion of the fullerene C-60, giving Delta(c)U(m)degrees(cr, 298.15 K) = -(25899.1 +/- 14.2) kJ.mol(-1) for this substance.
